Step 4: Launch USB Burning Tool & Load Firmware

Step 4: Launch USB Burning Tool & Load Firmware

  • Open USB Burning Tool.
  • Click File → Import Image.
  • Select your downloaded .img file.
  • Uncheck "Erase Flash" and "Erase Bootloader" (unless you are fixing a boot loop, then leave them checked).

Step 5: Connect the MX9 in "Mask ROM Mode"

This is the hardest step for beginners.

  1. Unplug the MX9 power.
  2. Insert the paperclip into the AV port (the round hole). Press and hold the reset button inside.
  3. Plug the Male-to-Male USB cable into the USB port closest to the Ethernet port (USB 2.0). Connect the other end to your PC.
  4. While holding the reset button, plug the power adapter into the MX9.
  5. After 3 seconds, release the reset button.

Success indicator: The USB Burning Tool turns Purple or Blue and shows "HUB2-1: Connected."

Step 6: Flash the Firmware

  • Click Start.
  • Wait for the progress bar to reach 100%. This takes 3-5 minutes.
  • The box will show "Success."

2. User Interface (UI) and Navigation

  • Launcher: The stock firmware typically uses a standard "TV Box" launcher. It is functional, offering large tiles for apps like YouTube, Netflix, and the File Manager. It is not customizable but is simple enough for non-tech-savvy users.
  • Responsiveness: On Android 7.1.2, the UI is reasonably smooth. The RK3229 chip is not powerful, so expect slight lag when opening apps or navigating heavy menus. The 1GB or 2GB RAM variants (common for this box) handle the OS adequately, but background processes will slow things down quickly.
  • Language Support: As a generic Chinese import, the firmware includes full multi-language support, though some system prompts or pre-installed bloatware may contain translation errors.
